Hi forum,
My pleasure to be here, I am very happy to see you all.
I have been hired recently by a company and this is the first time I use jetson and am totally new to GPU stuffs things.
Will you please direct me to place that I can learn the general terms and jargon related to GPU and JETSON tx2 and other related subjects?
More importantly I am trying to install a good IDE and programming environment to be able to learn and update my C programming knowledge and due to lack of experience in ubuntu and lack of knowledge in entire nvidia I am badly stuck. I get error message while installing necessary stuffs and all sorts of error when wanting to do even a simple program.
Any help and recommendation will be greatly appreciated.
Something very simple which will make your life easier is knowing about ssh and copying files to/from the running Jetson (the “scp” command is sort of like “cp”, but works via ssh to/from remote systems).
Another tip is to understand that there are times when you need the super user authority. The account “root” is normally the account which you would do this from, but Ubuntu locks this account. There is a second mechanism every Linux system has, but which is normally mandatory for Ubuntu: The “sudo” command. To run a single command as root, e.g., to list files: “sudo ls”.
To drop into a root shell for a series of commands (there are alternative methods to do this as well):
sudo -s
...do some things as root/root authority...
exit
Note that ssh keys are actually more secure than passwords. The root account itself can be unlocked, then ssh keys added for just your host, followed by re-locking the account (the lock is against password login, not root authority…an ssh key can be used instead of sudo).
You would have to give more details of what command gave an error, and what the error was, but another detail you might be interested in learning more about is remote execution, especially over ssh.
When you log in to a remote Linux system to run a command there are basically two categories of commands: Either something non-GUI executing entirely on the remote system, or else something with a GUI which displays the remote system’s GUI on the local system’s graphical desktop. When you get a chance to post about the error or command, also always note if this is being done via a remote connection or locally at the terminal. More details won’t be possible until we know what it was which produced the error.
If you have an issue getting things working as you need on a TX2, then this is the right place. In some cases someone might say “we don’t know, you’ll need to ask the producer of that 3rd party software…”, but nobody will worry about whether a TX2 question is good or bad.
You can do full development directly on the Jetsons for most purposes, although there are a few fringe case exceptions.
If you wish to flash to a new release, then you do need a Linux/Ubuntu host PC. You have the option of cross compiling and developing from a Linux host.
